Transmutation Timescales for Dark Matter Induced Collapse of Compact Stars into Black Holes
H. A. Adarsha, Chandrachur Chakraborty, Sudip Bhattacharyya
Ultra-heavy asymmetric dark matter (DM) particles captured by compact stars can thermalize, self-gravitate, and collapse to form an endoparasitic black hole (EBH), whose subsequent…

Magnetically arrested transmutation of a compact star
H. A. Adarsha, Chandrachur Chakraborty, Sudip Bhattacharyya
We introduce a novel mechanism -- Magnetically Arrested Transmutation (MAT) -- which could be a viable model to account for the observed over-representation of magnetic white dwarf…

Accretion inside astrophysical objects : Effects of rotation and viscosity
H. A. Adarsha, Chandrachur Chakraborty, Sudip Bhattacharyya
Sub-solar mass black holes could show up in gravitational wave observations in future and near-solar mass black holes might have been involved in the events GW190425 and GW190814.…
